I keep track of life in org-mode.
** TODO [P1] Perf
*** DONE Finish port to openwrt
**** DONE Patch 4.4
If anyone wants to play with perf for 4.4 on the linksys 1200ac, the
patches work but are sketchy.
**** NEXT Patch Kernel 3.18, 4.0, 4.1
*** Start getting valid cpu statistics back friom cake vs htb + fq_codel
* TODO Get faster delay box
Current box dies at 200mbit.
Goal: drive things past a Gbit with delay
** Use new boxes to test with?
** Try netem with a modern kernel?
** Buy a faster box for delay
* Finish cake testing
** DONE Collect behavior of all existing models at various RTTS
*** Codel differences - nearly non-existent - and invisible with fq
** NEXT Evaluate behavior at really low speeds
Does the inhibit actually work?
What does ECN do to everything else?
capture count variable from tc_iterate
std tests - rrul, tcp_upload, tcp_download
USE: pie, fifo, codel, cake flowblind, bcake flowblind, fq_codel, cake, bcake
VOIP test useful
*** 64k symmetric
*** at 384k/64k
** Shared codel variables?
** Rip out rate estimator.
** Rip out unneeded statistics
** Substitute existing codel algorithm
** interval >> 4?
** peel at quantum
*** Other schemes
Peel at 250us backlog
Keep the device busy
Peel at some work load
Peel at quantum
** increase quantum to 2 packets at highest rates per sch_fq
** dual queue?
** Fix stats
Oct 15th notes on efficiency
> Why don't you just have a struct with all the stats, and then an array with this type of struct size TC_CAKE_MAX_TINS ?
That's how it was until a couple of days ago. We ran out of space to
add new stats that we wanted while retaining binary backwards
compatibility with the userspace parser. The new arrangement
specifically avoids that trap.
** Finish and Fix API
* Retest Cake
** Very low bandwidth
** Long RTTs
* Merge upstream
** Cake 2
Let's go make home routers and wifi faster! With better software!
